Nope. Several a couple of episodes have had roadblocks edited out. THe most famous one is the very first leg of the very first season when in Sangway village before checking they have to eat a Ostrich egg.

And I don't think this leg was edited due to being spoiled.

I think it was edited to make room for all the conflict between the players.

It makes me curious: was that the only task cut out? We saw a few shots of Grand Bassin at the beginning of the show, but no more. And nothing about a waterfall (if Chamarel was it; we may have to keep looking).

In the map I mentioned earlier, you can see many of the southwest tasks were close together: the "pirate island" (Ile Aux Benitiers), Case Noyale, and the salt flats (I couldn't find the particular one, there are too many to choose from and I didn't see any place signs). The Chateau Bel Ombre seems to be distinct from the village of Bel Ombre. It describes itself on the website as "...amidst elegant hundred years old French gardens at the edge of the golf course and at the foot of mountain." The only place I could find that matches that description is a golf course at the bottom of Morne Brabant (kmz attached).

FWIW, this pic of D/K opening the roadblock clue is clearly the exact same spot where Izabela shot her video. You can see the identical boats in the background in the video.

Must have been within walking/VERY short driving distance from the Isla Mauritia ship, as their hair is still soaking from the swimming task, and I believe they are wearing the same life jackets from the swimming task. The short distance would explain why the order of teams was not affected at all by the roadblack and made for an easy "edit-out."

The kayak task also makes more sense of Godwin's comment about "having enough of the sea" when the six-pack is making their Salt/Sea detour decision. They would have already done a swimming AND kayaking task.
